help with blacklabelads

Hello,
im new here, although ive been on the site before, ive only just registered.
I was wondering if anyone had any ideas. My problem is with 125000 adzone views my earnings have decreased from $40.00 per 7 days,(over $5 daily) to $22.00(under $3 daily), but nothing has changed on the site and the visitors are the same numbers as before. My site is adult, but i cannot think why the earnings have almost halved in about 1 1/2-2 weeks. Ive got popunders on the site from adultadworld, but im reluctant to put all my adverts from them cos i dont know whether their rates compare..
any help would be apprechiated
